New Hampshire primary 2024: Trump projected to win, Haley vows to fight on

At around 4:30 p.m., Americans for Prosperity Regional Director Greg Moore said on X (formerly Twitter) that he'd heard from sources in the New Hampshire secretary of state office that towns around the state had gone through more than 80 percent of GOP primary ballots available statewide, and that some towns were calling to ask for more to avoid running out. Polls in much of the state closed at 7 p.m Eastern, but a few places are open until 8 p.m.

Now, the Koch-affiliated AFP endorsed Haley to much fanfare earlier this cycle, so high turnout certainly would make Haley supporters feel hopeful about the number of independent voters taking part in the primary, who generally are more likely to support Haley than Trump. Still, ABC News's current total expected vote total in New Hampshire is 330,000 votes. Although that figure may change as the night wears on — it could go higher or lower — that many votes would represent nearly 30 percent of the state's entire voting-eligible population — that is, anyone who is eligible to register and vote. A turnout rate at that mark would be on par with the highest turnout in the state's modern history, which was the highly-competitive 2008 Democratic presidential primary.

Voters head to the polls in high-stakes primary

ABC News' Eva Pilgrim reports from a polling location in Londonderry, New Hampshire, as voters head to the polls.

Four years ago, Democratic primary voters faced a situation similar to Republicans today: they were choosing a presidential nominee to unseat an incumbent with a low approval rating. But there's an important difference. Democrats emphasized electability, and though Biden was few Democrats' top pick — having finished fourth in Iowa and then fifth in New Hampshire — he benefited from the perception that he would run well against Trump.

For today's Republicans, the situation is much simpler: Trump is both the overwhelming first choice and the candidate they view as most electable. In a November 2023 survey that I conducted with the pollster YouGov, I found that 66 percent of Republican primary voters nationally backed Trump, but also that 72 percent of them thought that Trump was most likely to beat Biden. Despite some polling showing Haley running better against Biden nationally, most Republican primary voters see no trade-off between backing their preferred candidate (Trump) and winning in November.

In 2016, New Hampshire bailed Trump out after a disappointing finish in Iowa. Trump lost the Iowa caucuses by 3 percentage points to Sen. Ted Cruz before going on to win the New Hampshire primary decisively, beating then-Ohio Gov. John Kasich by nearly 20 points.

This time around, Trump won Iowa with an outright majority, but polls suggest that the contest in New Hampshire may be closer, even if Trump wins. What changed?

For one, in the eight intervening years, Trump’s base of support has shifted in subtle but meaningful ways. In 2016, Trump was an insurgent candidate who was challenged on the right by Cruz. But having served as president, Trump now defines the party’s right wing, and he enjoys overwhelming support from some of the party’s core constituencies: evangelical Christians, people who identify as Republicans and older (white) voters. And those voters are more numerous in the Iowa caucuses than the New Hampshire primary, giving Haley more of a chance in New Hampshire than she had in Iowa.

For example, in 2016, Trump did equally well in New Hampshire with voters who identified as Republicans and voters who identified as independents. In fact, part of his 2016 appeal was to those who were somewhat disaffected with the two parties. But in Iowa last week, Trump did much better among Republicans (54 percent) than among independents (42 percent) — and many more Iowa caucusgoers were Republican identifiers (82 percent) than we are likely to see today in New Hampshire, where undeclared voters can participate.

Most New Hampshire GOP primary voters believe that efforts to remove Trump from the ballot in other states are driven by partisan politics, according to a January survey from the University of New Hampshire Survey Center/CNN. Seventy-four percent said that partisan politics factored into the decision to remove Trump from Maine’s primary ballot “a lot” or “some.” Eight percent said it didn’t factor in very much, and 10 percent said it didn’t factor in at all.
